Hurricane Florence made landfall on the 11th as a Category 1 Hurricane. A maximum sustained wind speed (10 minute mean) of 71 knots with a gust to 97 knots was recorded at one of our remote observing sites in St. David’s, however, only 59 (2 minute mean) knots was recorded at the airport. Despite the hurricane, the remainder of the month was mostly sunny with below normal number of days with measurable precipitation, slightly cooler air temperatures, and slightly above normal sea temperatures. Hurricanes Gordon, Helene and Isaac all passed well to the east.
Fine weather began the month of September, lasting into the 2nd. A very slow moving cold front brought thunderstorms, moderate to strong southeasterly winds, and showers through out the day on the 3rd. Showers associated with the front continued to fall on the 4th, with moderate southeasterly winds. A few early showers fell on the 5th, however skies cleared to mostly sunny, with light southwesterly winds. High pressure dominated on the 6th, with mostly sunny skies and light southerly winds backing east-southeasterly on the 7th.
Tropical Storm Florence, located
well east of the Windward Islands began to be monitored closely.
Conditions remained pleasant on the 8th, however by late
afternoon a Hurricane Watch was issued for Bermuda, as Florence was expected to
become a Hurricane and pass very close to Bermuda.
The first signs of rain associated with Tropical Storm Florence came in
the afternoon on the 9th. A
Tropical Storm Warning was issued. Winds
began to increase on the 10th as Hurricane Florence continued her
approach, with a Hurricane Warning being issued at 5:30 am.
Thunderstorms and showers arrived late morning, as winds increase to
strong from the east, gusting tropical storm force.
Suspected tornados damaged properties in the Western Parishes. Florence arrived on the 11th producing category
one hurricane strength winds beginning in the early morning, with showers and
blowing spray. Winds finally began
to ease to tropical storm force, with some clearing in the late afternoon.
The Hurricane Warning was replaced by a Tropical Storm Warning, finally
decreasing to a Small Craft Warning by the 12th, as skies cleared and
westerly to northwesterly winds became moderate to strong.
A few brief showers fell on the 13th,
while skies were a mix of sun and cloud and winds were light from the
east-northeast. Fair weather
settled in on the 14th, while light to moderate easterly winds veered
to the southwest by the 17th. Light
to moderate winds backed south-southwest on the 18th, while skies
remained mostly sunny, lasting into the 20th.
A cold front from the west and Hurricane Helene to the east caused mostly
cloudy skies and isolated shower on the 21st, as winds veered to the
north. Despite passing at a
distance greater than 400nm, Helene caused dangerous surf for Bermuda.
High pressure returned on the 22nd with mostly sunny skies,
while northerly winds remained moderate to strong.
Cooler, drier, and sunny conditions lasted into the 24th.
